This MIDDLE PRESSURE FAN is constructed with compact carbon mild steel plates for both the rotor and casing. The rotor features optimized blade angles and radial-type blades, engineered to generate stable medium pressure for industrial applications. Dynamically balanced and mounted on a cast iron central hub, it is directly driven by the motor shaft. The entire unit is enclosed in a dust-proof casing to ensure reliable, efficient, and durable operation in demanding environments.
